IP Address DIsplay/Attached Device Display 870 Series

Ok so this is my 870 series with RBS wirelessly connected and synced with MLO enabled:

Been like this for past 15 days. 

Just now connected them both via ethernet backhaul to the RBR. 1 XS505M and 1 GS110MX non manged switches in between:

Same wired configurations i've tested since Orbi 40/50 series using older 1Gb non managed switches and now since Orbi 960 series, when I bought the 10Gb supporting non managed switches. 

I have used 1 managed switch at the head between the RBR and RBS. RBR was in router mode and with a VLAN Tag of 4092, makes all ethernet connected RBS work. Even Guest Network works. There is a known issue with Orbi sytems running in AP Mode currently with RBS ethernet connected to a managed switch that causes the Guest Network to not work. I was advised by NG switch group this was a Orbi FW issue, not a switch issue. I also have seen this with other non NG branded managed switches as well. This is only in AP Mode with the Orbi RBS ethernet connected to Managed switches. Non managed switches doesn't produce this issue and is most easiest to resolve by putting a non managed switch in between the RBS and RBR while in AP mode. We have brought this to NG attention a while back and haven't got any feedback on it. I presume that NG may or may not want to resolve that as in general use, most home users don't have a managed switch, have the expertise to use a managed switch and using a non managed switch is a quick resolution for this. So if you feel that you want this to work, you'll need to make contact with NG support and present your findings and concerns. 

To help you figure out if your system is working on it's own with out managed switches in the mix, Try a non managed switch in between the RBR and RBS. Once thats tested, then try one managed switch in between the RBR and RBS. Set a VLAN ID tag on all ports of 4092 and see how it goes with the RBS. Router or AP mode should work, however Guest Network will not work in AP Mode in this configuration with a managed switch. 

Overall Ethernet backhaul does work. It goes get tested by others I know early on. With non-managed switches. 

Other that all that, yes, RBS don't report connected devices correctly on my system as well, something NG will have to fix if they choose to:

I believe this is a host name handling issue at the RBS and not a MAC address issue for the most part. These devices appear on the RBRs web page correctly. Something we have also brought to NGs attention. 

You can try to make it work the way you believe, however it's NG's product. Good luck in making that change. Not every product works as some users want them too. If it doesn't work as you want it to, then you may need to find something else that does.
